Cu2+ doped ZnO by green synthesis was successfully prepared by using a combination of the Sol-Gel-Sonochemical method. Duck egg albumen was used as an additive, a substitute for chemical additives, such as monoethanolamine (MEA) and diethanolamine (DEA). ... see more

Penelitian mengenai sintesis nanopartikel ZnO undoped dan doped Cu2+ telah dilakukan melalui metoda sol-gel, dengan menggunakan zink (II) asetat dihidrat sebagai prekursor, isopropanol sebagai pelarut, dan monoethanolamin sebagai zat aditif. Tujuan peneli... see more

In this work, pure ZnO and Cu-doped ZnO nanoparticles (Zn1-xCuxO, x = 3 at.%) were synthesized using the sol-gel method at three different calcination temperatures (TC = 773 K, 823 K and 873 K.). The particles were analyzed by atomic absorption spectrosco... see more

Copper oxide (Cu2O)-based heterojunction solar cells were fabricated by spin-coating and electrodeposition methods, and photovoltaic properties and microstructures were investigated. Zinc oxide (ZnO) and Cu2O were used as n- and p-type semiconductors, res... see more

Al-doped ZnO (AZO) nanodrums were synthesized using hydrothermal method at 80 °C for 20 h using precursor Zn(CH3COO)2·2H2O and Al(OH)(CH3COO)2 as a dopant by varying the addition of Al concentrations in the range of 0, 1, 5, 10, 15, and 20 mM. The variati... see more

In this study, La and Mg doped, and co-doped ZnO nanoparticles were prepared using the sol-gel method. The prepared samples were characterized by X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), energy dispersive X-ray spectro... see more

Glasses with compositions 59B2O3-10K2O-(30-x)ZnO-xBaO-1CuO were prepared using melt quenching technique. The effect of BaO content in present glass system doped with copper ion in place of ZnO has been studied with respect to structural properties. Raman ... see more

The structural and optical properties of Ni doped ZnO nanoparticles (NPs) prepared by co-precipitation method have been investigated. The X-ray diffraction pattern confirmed synthesized nanoparticles retained the wurtzite hexagonal structure. From FESEM s... see more

First-principle calculations have been performed to investigate the electronic structure and optical properties of ZnO co-doped with Nb and Ta. The three doping structures are set to: Zn0.9375Nb0.0625O, Zn0.9375Ta0.0625O and Zn0.875Nb0.0625Ta0.0625O. The ... see more
